No hydrophobicity, ceramic surface forms water films on the surface
making easy path leading to more flashover

Very excellent hydrophobicity

Self cleaning quality

No, dirty sand salt snow etc are easily attracted

Yes, due to hydrophobicity recovery characteristics

Tension strength

Good

Better during crimping technology

Maintenance

Needs maintenance like cleaning washing and greasing

Not required at all

Safety

Are easy to explosion and breakages due to high fragile properties
and stone throwing or gun shooting

Provide very high level of safety superior flexibility and
strength. not easy to break due to stone throwing or gun shooting.

The Polymer Insulator are made of glassfiber epoxy core rod,
silicone rubber shed and metal fittings.

The silicon rubber shed adopt the whole packing pressure technique,
and then to solve the key problem – interface electric spark
puncture, which would affect the reliability of composite
insulator.

Connection of the glassfiber rod and metal fittings, adopts the
pressure welding technique of the international advanced level, and
have the full automatic sound wave detection of defects system,
high intension, beautiful outline, small volume, light weight, and
the metal fitting of galvanization can corrosion prevention and
exchange used with porcelain insulator.

This product is reliable structure, can’t damage the core rod, and
take full advantage of the mechanical strength.
